Just a plain, old fashioned girl....in love with my old potato peeler. Really, would be lost without it. Just lost my 30+ year old microwave. Thought it was a luxury until it was no longer around. A new Sharp for less than $100 and breakfast is a breeze once more. The old Montgomery Ward appliance was much more than $100- and it lasted for over 30 years before giving up the ghost (so no complaints)
